Detailed Description
The invention will be further explained below with reference to the drawings and some embodiments.
In fig. 1-2, a novel battery electrode column includes a first column 1 and a second column 2, the second column 2 is made of copper, the second column 2 is integrally formed and sequentially divided into a first portion 3, a second portion 4, a third portion 5 and a fourth portion 6 from top to bottom, the first portion 3, the second portion 4 and the third portion 5 are all cylindrical, the first portion 3 and the second portion 4 have the same diameter, the third portion diameter is smaller than the first portion 3 and the second portion 4, the fourth portion 6 is conical, and the surfaces of the second portion 4, the third portion 5 and the fourth portion 6 are smooth surfaces; the first column body 1 is a tin alloy block which is cast and integrally formed, the lower end of the first column body extends into the battery, and the upper end of the first column body is provided with a groove 7 which is matched with the outer surfaces of the second part 4, the third part 5 and the fourth part 6; and tin layers are arranged on the outer surfaces of the second part 4, the third part 5 and the fourth part 6 and are welded in the groove 7 through the tin layers, so that the smooth surface of the first cylinder 1 is fully contacted with the second cylinder 2, and an electrode column with good electric contact and physical contact is formed.
In this embodiment, the first column 1 has a cylindrical structure and a diameter of 3-5 cm.
In this embodiment, the first portion 3 and the second portion 4 have a diameter of 2-4cm, and the third portion 5 has a diameter of 1-3 cm.
In this embodiment, the second cylinder 2 is made of copper for the purpose of good conductivity, and the first cylinder 1 is made of tin alloy for the purpose of corrosion resistance, so that the first cylinder 1 extending into the battery has a longer service life.
In the embodiment, in specific implementation: the second part 4, the third part 5 and the fourth part 6 are stained with tin water to form a tin layer, then the tin layer is placed in the groove 7 and is welded and fixed with the inner wall of the groove 7 through the tin layer, after the tin layer is welded and fixed, a certain torque can be applied through a torque wrench to torque the second column body 2, when the tin layer can be twisted, the contact degree of the first column body 1 and the second column body 2 is insufficient, poor contact, heat generation and other potential risks exist, if the tin layer cannot be twisted, the first column body 1 and the second column body 2 are in full contact, the contact degree of the smooth surface of the first column body 1 and the second column body 2 is checked, and therefore the first column body 1 and the second column body 2 are guaranteed to have good electric contact and physical contact.
